Bad ammo sucks. I bought some 5.56 ammo last year called Hot Shot Elite, its made in Romania, and its total crap. I got two shots off with this ammo before my Stag AR15 failed to eject the second round, and I didn`t have a cleaning rod with me to knock out the case. When I got home and was able to remove the case from the chamber, the rim of the case was torn were the extractor tried to grab it. All of the fired cases from this ammo show some type of deformation around the base of the case, like the brass is to soft, or something. I still have six boxes of this crap, and I wont be saving any of these cases for reloading.
